sequence of code inside function changed (?)

There is no difference between the two types at the moment...

But:

function a() {
  function b() { foo(); }
  doSomething();
}

What happens now

• A variable for a is created
  
• Inside it, a variable >cod it set to the function's code.
  
  

Result:

var a = { ">cod" : "{\n  function b() { foo(); }\n  doSomething();\n}" };

What will happen in a later version of Espruino

• A variable for a is created
  
• The function's code is parsed, and the Espruino recursively does the same thing on any functions inside the current one
  
• Inside it, a variable >cod it set to the function's code, minus any functions defined inside it.
  
  

Result:

var a = { 
 "b": { ">cod" : "{ foo(); }"} 
 ">cod" : "{\n  doSomething();\n}" 
};

Does that make more sense? If you used var b = function() { ... } exactly the same thing would happen in the future as happens now (what's described above).
